Fig. ll pins in each rowbeing arranged staggered in 5o represents an end view of Fig. l0.Fig.'l2 relation to the pins in an adjacent row, all rool the said pinsG' and H', however, in their respective rows being arranged insubstantially parallel longitudinal lines, as is best seen in Fig.10,1he bases of said pins being secured in the said upper die in theinclined portions of the transverse grooves in every instance, so thatthe longitudinal space between any two adjacent pins will always embraceeither the deepest or the highest portion of one of the transversegrooves in the face of said upper die, certain of the pins nearest thefront of the die being prolonged for a purpose to be referred to. Theends .T' of the two rows of pins G' are bent in the same direction, inthe present case to the left, and the ends of the two rows H' are bentin the opposite direction, in the present inst-ance to the right, asseen in Figs. 7, 10, and 11, so that when the upper die descends andcontacts with the lower one, it a hair-pin K5 be thereon, it will beseen that each leg of the same will be engagedv by the pins G and H',the points of the same being bent, so that their bodies do not come incontact with the wire until they have entered the holes H5 and J in thelower die, the latter having transverse grooves and ridges to correspondwith the contour of the upper die.

K' designates an angle shaped bracket which is secured to the head V andhas the portion S', which holds the stripper L' tightly against thebottom thereof, as seen in Fig. let, said stripper being employed topush the hairpins off from the upper die as the latter ascends. The saidstripper is shown in detail in Fig. 13 and consists of the body-pieceM', having the downwardlyT depending leg or blade l5'. extend from eachend of said body-piece and enter similar body-pieces Q', which have thedownwardly-depending legs R'. The parts are shown in operative positionin Fig. S especially, and it will be noticed that the legs R' areadjustable laterally to allow dies of diierent lengths to be used, theopenings C' C' in the head B' being made somewhat wider in practice thanherein shown.

T' designates the lower die, which is secured to the bed U' in anysuitable manner and has a projection V', which is directly under the endslots E' and C', the object of said projection being to keep the ends ofthe pin ata proper distance apart as the same is bent into a U shape,and to also assist in shaping the pin, as is evident from Figs. S and 9,the working face of said die T' being provided with the transversegrooves and the staggered holes in t-he sides thereof, the deepestportions of said die T' being directly under the highest portions of theupper die D', and the ends J of the pins therein being vertically overthe holes H5 and J 5, as has alreadybeen stated. v

L5 designates an opening in the bed-plate A, adjacent the bed or anvilU', through which the pins are discharged into a suitable receptaclebelow. Z' designates a plunger P' designates pins or studs which.

which is vertically movable in a hole in the rear of said bed U', and A2designates a spring thereunder, said plunger normally extending upwardlya short distance above the upright portion C2 of the angle-piece B2,which is suitably secured to the bed U', said upper end C2 beingpreferably shaped as shown in Fig. 8 for the reception of the wire D2,which is shown in Fig. 9 in the act of being fed between said end C2 andthe plunger Z', the latter being depressed by the upper die when thesame reaches the bottom of its stroke.

E2 designates the front end of a reciprocating bar L5, said front endhaving a recess in which are pivotally secured at H6 the links F2 F2,which have journaled in their front ends the rollers H2, which are keptin proper position in the present instance by their contact with thesides of said recess, which is effected by means of the U-shaped springJ2, the ends of which engage the links F2, as seen in Fig. 9.

K2 designates grooves in the periphery of the rollers H2, whereby thewire is held in position while being bent into U shape, as shown in Fig.9.

The end L2 of the said bar L5 is pivotally attached to a rod M2 at apoint intermediate the ends of the latter, as shown in Fig. 3, p

said rod M2 having its lower end pivotally attached toa suitable fixedpoint N2, while its upper end carries a stud Q2,Y which is actuated bymeans of the inside cam-groove R2 of the cam-wheel S2. The periphery ofsaid wheel S2 is recessed at T2, h 5 and N5, Fig. 4, designating theextent of said recess. V2designates another working face or incline onsaid cam-wheel S2, the radius ot' the short arc V2 M5 being obviouslyless than the greatest radius oi said wheel.

rlhe end U2 of the lever P5 is Vprovided with a suitableantifriction-roller Q5, which is always kept in contact with theperiphery of the cam-wheel S2 by means of the plunger X2, which isplaced thereunder and rests on the spring Y2. The lever P5 is fulcrumedat W2, and it will be seen that the revolution of the cam-wheel S2 inthe direction of the arrow will impart to the end Z2 of said lever twosubstantially vertical movements of varying extent, the object of whichwill be made evident. Near said end Z2 of the lever P5 is secured theangle-shaped piece A5, which has a horizontal lateral extension B5,which is located behind the dies and which may be made in sections andhas its extreme right-hand end R5 turned downwardly. C5 designates twopins attached tothe under side of said extension B5, which pass throughopenings in the stationary plate D5, which is secured to a suitableportion of the bed A.

M6 designates a plunger which rests on a spring J5, inclosed in acasing, the head of said plunger bearing against the'end of theright-hand pin C5, as seen in Fig. G, so that the upward movement of theplate or extension B5 is always assured at the proper times.

IOO

IXO

K4 designates an adjustable stop adjacent the bed U. To the under sideof the lefthand end of the said extension B3 are attached the pins S5 S5and T5, the latter pin being set a little behind the other two, whichare in line, so as to form guides for the wire D2 before the same isdepressed by the pins C3 to the level of the grooves K2 in the rollersH2 prior to being bent into U shape, as in Fig. 9.

U5 designates a block which is attached to the end Z2 of the lever P5,the said block having in its upper surface a groove V5, corresponding toa similar groove in the under side of the stationary plate D3, so thatthe wire at certain times will be tightly gripped therebetween. V5designates grooves in front of said block U5, which allow the pins S5 toenter therein.

The rolls H2 are journaled in a suitable frame X5, the upper portion Y5of Which is extended to the right, as seen in Fig. 7, the same beingremoved in Fig. 9 for convenience of illustration, the oliice of thesame'being to assist in moving and guiding the wire before it is rstbent into U shape.

Referring now to Figs. l and 2 especially, G3 designates rollers overand between which the wire Dzis fed,which after leaving the same passesinto the guide H3,the same consisting of a hollow tube supported in thestand J 3. K3 designates asector-shaped plate which is attached to aside of the gear G,the arc portion of which at times contacts with theperiphery of the disk L3 when the parts are in the positions shown inFigs. l and 5. The said disk L3 is attached to a side of the gear M3,which meshes with the gear G, said gear M3 being suitably journaled andthe disk and sector bein gin the same vertical plane. N3 designates agroove in the periphery of said sector and disk, and

when the wire is fed thereinto from the guide H3 and the arcs are incontact, as seen in Fig. l, the wire will be fed along into and throughthe guide P3, which is suitably attached to the bed A, and thence itpasses into the hollow spindle Q3, which is kept from turning by meansof a set-screw in the arm R3, the latter being attached to the top S3 ofthe upright portion X3 of the stand T3, the latter being capable oflongitudinal movement in the ways U3, the movement in one directionbeing caused by the engagement of the shoulder V3 of the rod W3 with theupright portion X3 of said stand T3, said rod being actuated by meansofv the pivotal connection of the arm Y3 of the bell-crank Z3 with theknuckle A4 on the end ot' said rod W3, the other arm B4 of saidbell-crank having a stud O4 therein engaging the walls of the cam H, asseen in Fig. 2, said bell-crank Z3 turning freely on the stud D4. Theleft-hand end of the stand T5 has a downwardly-turned portion E4, inwhich is the threaded bolt F4, which can be locked in any desiredposition in the usual manner. G4 designates a spring one end of whichabuts against the shoulder V3,

while the other end is in contact with the other vertical portion H4 ofthe stand or frame T3, and it will be seen that a movement of the rod73, Fig. 6, to the left will cause a like movement of the stand T3, theextent of said movement being determined by the throw given to thebell-crank Z3 by the cam H, while the stands movement to the right iscaused by the contacting of the spring G4 with the .upright portion H4,said movement being limited by the contact of the bolt F4 with somesuitable fixed point, which may be a crossbar (not shown) connecting theguides U3 U3, an additional longitudinal movement of the rod W3, whichpasses freely through the uprights X3 and H4, being permissible byreason of the compression of the spring G4, as is evident. J4 designatesthe right-hand end of the rod W3, which after passing through theupright H4 is pivotally connected with the lever K4, one end of which ispivotally attached to the ear L4 on theV stand T3, the other end of saidlever being forked and having-the inwardly-projecting studs M4 M4,whoseends'engage the sides of the groove N4 of the sleeve A5, which may havea portion of its right# hand end cut away, as seen in Figs. l and 2especially.

Referring now to Fig. G especially, P4 designates a pulley which ismounted on and secured to the sleeve Q4, so that the latter revolvestherewith, said sleeve having in the portion S3 the adjustablecone-shaped bear-l ing R4 for the purpose of taking up wear, the conicalbearing S4 in the top portion U4 not being adjustable. The said sleeveQ4 has an extension V4 projecting to the right beyond the bearing S4 andhas secured thereto the cylindrical shell W4, one end X4 of which isclosed, except for an opening in the middle, and thus incloses the endof said extension V4 and also the end of the sleeve Y4, which does notrevolve and forms a bearing for the outer sleeve Q4, said sleeve Y4resting upon and inclosing the aforesaid hollow spindle Q3, throughwhich passes the wire D3. Z4 designates a longitudinal split near theend of said spindle Q3, the end of the latter being made flaring orcone-shaped at A5, while the adjacent end B5 of the inclosing sleeve Y4is beveled to correspond. The left-hand end of said sleeve has thedepending arm C5, which is forked, so as not to interfere with themovement of the rod W3, and is engaged by the bifurcated end D5 of thelever E5, which is fulcrumed at F5, the other end having a stud G5,which is engaged and actuated by the sides of the cam M, as shown inFig. 2. The cylindrical shell W4 has a longitudinal spline O3 immovablyattached thereto, which enters a longitudinal slot in the sleeve A3,thusforming a guide'and a bearing therefor, as shown in Fig. 6. The saidsleeve A5 has also an inclined portion B6, which is adapted to ride upona similar inclined face of the movable block D3, in which is journaledthe cutter E5, which has its cutting edge V-shaped, so that IOO IIO

IZO

the wire is simultaneously cut and sharpened or pointed. F6 designatesan immovable block having a groove therein corresponding to the cuttingedgerof the cutter E6, and G6 designates a bar over the end of thedevice, said bar having an opening for the passage of the wiretherethrough, as has also the closed end X4 of the cylindrical shell W4,it being obvious that the parts A6, D6, F6, and G6 may be assembled inany suitable manner, it only be-A ing required that the block D6,carrying the cutter E6, be capable of being moved to and from the blockF6 by the engagement of the inclined face B6 of the sleeve A6 thereintoas said sleeve is reciprocated back and forth on the spline C6.

The operation is as follows: Referring to Fig. 1, first suppose thesector K3 to be revolved in the direction of the arrow until the pointN6 contacts with the wire D2, which is being fed through the guides H2and P2 to the right, and at the same time the edge M5 of the recess T2of the cam-wheel S2, Fig. 4, which revolves in the direction of thearrow, contacts with the roller Q5 of the lever P5, depressing the sameand raising the end Z2 into the position seen in Fig. 4, the upperportion of the block U5 being nearly in contact with the wire D2, whichis now between the stationary plate D2 and said block U5. At about thisinstant the rolls H2, Figs. 3 and 9, begin to be moved forward by meansof the connections shown particularly in Figs. 3 and 4 and bend thelength of wire which has been already cut off and depressed to a pointin front of said rolls into the U shape shown in said Fig. 9. At aboutthis instant the upper die is caused to descend into the position shownin Fig. S, and it will be evident that the transverse grooves in thefaces of the said dies will give to each limb of the pin a curva.

ture in one direction, while the engagement of the rows of pins G' andH', whose ends are turned outwardly, as seen i n Fig. 11, with the limbsof the pin, the pins being arranged staggered in relation to each other,as shown in Fig. 10, will give the limbs a curvature in anotherdirection, the result being the production of a pin P6, as seen in Fig.15, a portion of a limb of said pin having its convolutions inclined inone direction, as Q6, while another portion of the same limb R6 has itsconvolutions in a reversely-inolined direction, as described in PatentNo. 395,582, above referred to. The pin having been bent into the shapedescribed, the upper die rises, and the pin is pushed therefrom by thelegs N' and R' of the stripper L', Fig. 13, which is stationary, thesaid stationary legs passing through the slots C in the head B as thelatter ascends, (see Fig. 8,) while the device E3 guides the pins asthey fall down'through the opening L6, Fig. 4. At or about the instantthe upper die begins to descend the bellcrank Z3, Fig. 2, is moved byits cam, thereby moving the rod W3, Figs. 1 and 6 to the right, and bymeansof the spring G4 and the shoulder V2 and the other connections thestand T6 is moved to the eXtreme right as far as the bolt F4 willpermit, carrying with it the sleeve A6 and its adjuncts, and when thesame have reached this point the forked end D5 of the lever E5, Fig. 2,engages the depending arm O5 and moves to the right the internal sleeveY4, whereby the split ends A5 of the .hollow spindle Q3 are pressedtogether by reason of the contact of the cone-shaped ends thereof, whichslide on each other, Fig. 6, and will tightly pinch the wire D2therebetween. At this instant that portion of the wire between the plateD3 and block Z2 is tightly gripped by the engagement of the inclinedportion V2 of the cam-wheel S2 with the roller Q5, Fig. 4, the lattermovement being shown in said figure in the act of taking place. The wireis now gripped tightly on each side of the cutter E6, Fig. 6, and, thepulley P*l constantly revolving, further movement of the rod NVS to theright causes the sleeve A6 to move in the same direction, and by reasonof the inclined faces in contact at B6 the block D6, carrying the cutterE6, will be moved toward the block F6, simultaneously cutting o'if andpointing the wire, the proper` length of the same having been measuredoft' by means of the stop K6, the bent end R5 of the extension B6assisting to guide the wire when the latter is depressed, and the sectoror feeding device K5 is now in about the position seen in Fig. 5. Theproper length'of wire having been cut off, and the upper die having madeits descent and ascent, and the bar L5, carrying the rollers H2, havingbeen moved to its eXtreme rear position, the plate or extension B3 iscaused to descend into the position shown in Fig. 7, the edge N5 of therecess T2, Fig. 4, having now reached the roller Q5, the cam-wheel S2revolving in the direction of the arrow. The spring Y2 forces upwardlythe end U2 of the lever, thereby depressing the extension B5, as stated,thereby carrying the wire D2, which has just been cut off to the properlength, downwardly to a level with the groove K2 in the rolls H2, thepins O3 engaging the same, and the wire being held in its properposition by means of the staggered pins S5 S5 and T5, Fig. 6. stant thebar L5 moves forward, carryingits rollers H2, which bend the wire whichhas just been passed between the points B2 and Z', Fig. 9, into the Ushape,'the ends being kept at the proper distance apart by theprojection V. At about this instant the upper die descends and the pinis compressed into the shape shown in Fig. 15, as has been alreadydescribed. As kthe upper die descends the stand T3 is moved to theright, the wire is gripped on both sides of the cutter, as has beenexplained, and at substantially the same instant the rolls H2 begin tomove backward and reach their extreme back position just before theupper die ascends, it being remembered thatwhen the wire is being cnt itis above said rolls, and the latter begin to move forward just as theplate B3 is depressed, car- At this in-V f rrr IOO IIO

rying down the length of wire which has been cut off, the initialdownward movement of the upper die being substantially simultaneous withthe initial backward movement of the rolls H2. After the vire has beencut the continued revolutions of the cams, ttc., return the stand T3 andthe parts carried thereby to their left-hand position, the spring G4assisting somewhat in the return movement. The wire is bent intohorseshoe shape at about the same time the stand T3 and its adjunctsmove to the right, and the spring-pressed plunger MG assists inrendering the upward movement of the plate B3 more positive.

It will of course be understood that hairpins of different sizes may bemanufactured by the above-described machine by altering the dies andadjusting the other parts of the machine according to requirements, andit will further be evident that hair-pins of the usual U shape may begiven the reverselyinclined convolutions described by compressing thembetween the dies shown in Figs. 9 and l0, and we do not therefore desireto limit our invention to the successive operations of the several partsof the machine in every instance.

lt is of course obvious that the various functions of the several partshereinbefore referred tofviz., the feeding, cutting, and pointing,depressing, bending, and shaping the wire-may take place atslightly-different intervals in relation to each other than has beendescribed, and it is also evident that modications or changes may bemade, such as may suggest themselves to the skilled mechanic, which willcome within the scope of our invention, and we do not therefore desireto be limited to the exact constructions we have herein shown anddescribed.
